Specification of Letters fatent. A 1' Application filed November} .8 1909i Serial No. 526.9%.

To all 'lchom 2' t ma y concern Be it-kn'ow'n that. I, ArGvs'rrx-NonMA-Xn, citizen-of the Republic of France, residing at Le Havre, Department of the Seineriferieure, France, have invented certain g-new and useful Improvements in Liquid -Fue'l Atomizers; and I- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to-which it appertains to make and usethe same. A

a This invention relates to fuel atomizefs or pulverizers for spraying thelitjuid combusemployed in heating boilers and the li te.

The inventionhas for its object to provide an improved device of such character wherein the liquid is conducted to the ejection chamber through a number of passages arranged approximately tangentially to the "wall of the ejection chamber. The liquid therefore assumes a rapid whirling movement or gyration. An auxiliary valve is employed which is adapted to' feed less fuel to the furnace than the main valve, and by valves, numerous adjustments may be obtained to fulfil certain requirements.

' Theinventionis illustrated in the accompanying drawings, in which I Figure 1 is a longitudinal section of one form of the invention; Fig. 2 is section taken on the line B-B of Fig. 1.

The atomizer is provided with an annular chamber 1 to which the fuel is conducted from any suitable source of supply through the inlet 2.

A sleeve 16' is secured to the end of the casing of the atomizer preferably by the cap 6 which clamps a flange 7 of the sleeve 16 tightly against the extremity of the casing. The sleeve 16 has an interior annular e ection chamber 4 and an ejection orifice 5. Passages Wall of the ejection chamber 4 conduct the fuel from the chamber 1 to the said ejection chamberl, Sliding in the sleeve 16 and a longitudinal bore 8,"is a sleeve forming an obturator or valve 9 adaptedto cooperate with the orifice 5 to control the flow of fuel therethrou h. The valve 9 carries a ring 1? between which and the end of the bore a spring 10 is interposed, which acts tokeep 'operates with an orifice 14 formed in the valve 9. The orifice zl liisqireferablw what smaller thancthe orifice 5. sea -o' peimit a. smaller amountt'of fueltopa'ss:therethrough. An ejection t amller 11 is-prefer- 8.l)l f01ll1Q(1ll1 the wa li'isleeve' S and t-angentlally arranged passages IQ cQnduetTth fuel from the chamber ot-heinnerinost chamber. 11. An annular %sliQuld'er '-18, formed on the valve 13} hasa certain amount of play in the valve sleeve 9 so that said valve 13, when moved longitudinally to the left in the drawing, by means of the knob 19 or similar operating means, will open the orifice 14, but the moigement of valve 13 will have no effect on the valve sleeve 9 until the shoulder 18 abuts against the ring 17, lVhen said shoulder 18 so abuts against the ring 17 the valve sleeve 9 is moved against the action of the spring to open the orifice 5.

From the foregolng description, it will be seen" that during the kindling period, a slight actuation of the valve.13 will open the auxiliary or smaller orifice 14, but the main valve 9 will remain operative to preventthe passage of fuel. through orifice 5. The fuel then passes from annular chamber 1 through the tangential passages 3 into the larger ejection chamber 4, then through the second set of passages 12 into the innermost,

I chamber 11 from which it passes through the discharge orifice 14. hen it is desired to admit more fuel to the furnace, the valve 13 is actuated a greater amount and the shoulder 18 abuts the ring 17 .to open the main valve 9. It will be noted that when the valve 9 is actuated, the passages 12 are closed by the sleeve 16 thereby cutting off the supply of fuel to the innermost chamber 11 when orifice 5 is open.

hat I claim is 1. An atomizer for liquid fuel, comprising an ejection chamber having a discharge passage or conduit, an interior obturator for said passage communicating with said chamber and having a discharge passage alined with said first-named discharge passage, and means controlling the discharge p: ssage of the ohturatcr and also operative to adjust said obtura or with respect to said first-named discharge passage. t

27311 atomizer for liquid fuel. comprising an ejection chamber having a discharge passage or conduit, an interior ohturator for said passage communicating with said chain-- frame may be made of any suitable material,

and While I have shown the central open-V ing therein as rectangular in form, it will be understood that other forms for said opening may be adapted, and other changes in and modifications of the construction herein described may be made, within the scope of the appended claim without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention What- I claim as new and desire to secure by Let-- tiers Patent is A photographers mask consisting of a frame sheet of thin opaque material provided with a central opemng around which and in one side of said frame sheet is a groove adapted to receive a sensitized card or sheet, the other side of the frame sheet being provided at the corners thereof with pockets adapted to receive the corners of a negative and by which said negative is held in position and positioned with reference to the sensitized card or sheet.

In testimony that I claim the foregoingas my invention I have signed my name in presence of the subscribing witnesses this 15th day of August 1912.
